Package Type

General Description:

The TC32M is a fully-integrated processor supervisor

in a 3-pin package. It provides three important func-

tions to safeguard processor sanity: precision power

on/off Reset control, Watchdog Timer and external

Reset override.

On power-up, the TC32M holds the processor in the

Reset state for a minimum of 500 msec after VDD is

within tolerance to ensure a stable system start-up.

Microprocessor sanity is monitored by the on-board

Watchdog circuit. The microprocessor must provide a

high-to-low level shift (through an external resistor

divider) on the RS pin of the TC32M. Should the

processor fail to supply this signal within the specified

time-out period (typically 700 msec), an out-of-control

processor is indicated and the TC32M issues a

processor Reset as a result.

The output of the TC32M can be wire-ORed with a

push-button switch (or electronic signal) to override the

TC32M and unconditionally reset the processor. When

connected to a push-button switch, the TC32M

provides contact debounce.

The TC32M is packaged in a space-saving TO-92 or

SOT-223 package. It provides all of the functionality of

the industry standard TC1232 in a smaller, lower cost

configuration.
